So, I owned the plastic arm hydrometer which has been reading sg
of 1.023 - - I just got a refractometer today. It is giving me a reading of 1.029!!!! Oooof! If my hydrometer was really that far off, would things survive? Maybe this might explain the disappearance of 2 peppermint shrimp.
Anyway, I tested ro
water and it did read at 0, so I'm assuming the refracto is correct.
I guess my question is - how dangerous is 1.029? I'll be lowering it slowly over the next couple days. Oh, and would high sg
promote hair algae growth?
